Changes to GRE General and Physics subject test scores starting the admission cycle for the 2022-2023 Academic Year
July 2021

The Physics and Astronomy Department has decided that, starting with the admission cycle for the 2022-23 Academic Year (i.e., Fall 2022 start of the PHD or MS programs), GRE General and Physics subject test scores are no longer required, will no longer be accepted, and will no longer be considered in the evaluation of graduate applications. In determining the admissibility of a prospective graduate student, the department attempts to carefully weigh all relevant factors, including transcripts of academic work, three letters of recommendation, a resume/CV, research experience, a personal statement, and official TOEFL, IELTS, or Duolingo English Test (if applicable). A holistic approach to admissions is taken, carefully weighing all components of the application to make the best determination about which students will be a good fit in our department. The Physics and Astronomy Department is strongly committed to creating an inclusive graduate community whose members feel welcome and valued. However, we also recognize that the Physics and Astronomy communities have much work to do towards this goal. We encourage anyone interested in our programs to apply.

Tufts Astronomy Faculty Join Prime Focus Spectrograph Project
April 2019

Associate Professors Danilo Marchesini and Anna Sajina have joined the international team responsible for building the Prime Focus Spectrograph (PFS). The PFS will be annexed to the Subaru Telescope at the summit of Mauna Kea, Hawaii and allows simultaneous spectral observation of up to 2,400 astronomical targets using a state-of-the art fiber system, fiber positioner, four spectrographs, and a Wide Field Corrector (WFC). As part of the PFS Northeastern Participation Group (NEPG), Professors Marchesini and Sajina are guaranteed 300-350 nights of instrument access over 5-6 years with immediate access to the data generated. Access to such data will assist with future research and grant applications for Tufts faculty, post-docs, and students. Sajina and Marchesini will primarily study galaxy formation and actively accreting supermassive black holes, but the instrument also allows other groups to study different areas pertaining to dark matter, dark energy, and galaxy history. PFS testing will begin in 2020, and it is expected to go live in late 2021 or early 2022.

Tufts Physics Alumna Wins AIP Science Writing Award
December 2017

The American Institute of Physics has announced the winners of its 2017 Science Communication Awards for Books, Articles, Writing for Children, and Broadcast and New Media. The Articles prize was awarded to Natalie Wolchover for "What No New Particles Means for Physics," published in August 2016 in Quanta Magazine. Natalie studied physics as an undergraduate at Tufts and is currently a senior writer at Quanta Magazine specializing in physical sciences. The judges found Wolchover's article to be "well-crafted," in which she undertakes "a clear explanation of nuclear and high energy physics' Standard Model crisis." Her article took a creative and bold stance on scientific exploration, and "her voice is confident as she develops a solid narrative throughout her article. "[Wolchover] does a beautiful job of creating drama and intrigue from what amounts, essentially, to no new findings and bravely and simply states the crux of the crisis," the committee noted. This brewing crisis of particle physics — a lack of new particle discovery — inspired the article. Read the announcement from the AIP website and check out Natalie's alumni bio.

Former Member of Tufts' Department of Physics & Astronomy Rainer Weiss Wins the 2017 Nobel Prize in Physics
October 2017

In February 2016, the LIGO and VIRGO collaborations created a shockwave when they announced the first observation of gravitational waves, predicted 100 years earlier by Albert Einstein. Since then, this discovery has received a lot of media attention (for example this New York Time article), captivating the public imagination. The LIGO and VIRGO experiments are based on laser interference techniques developed by Rainer Weiss in the 1960s. Prof. Weiss later co-founded the LIGO project and obtained NSF funding for initiating the project. In reward for his decisive contributions to the LIGO detector and the observation of gravitational waves he was awarded half of the 2017 Nobel Prize in Physics, the other half being shared between Kip Thorne and Barry Barish. Rainer Weiss spent most of his career as a faculty member at MIT, but his first faculty appointment was as an assistant professor at Tufts from 1962 to 1964. He is the second Nobel laureate that worked at Tufts, joining particle physicist Allan Cormack in this very distinguished category. Both were members of the Department of Physics and Astronomy!

Project Information

Thermal Analysis of Polymers in Germany
October 2016

Over the past few years Professor Peggy Cebe has been collaborating with Professor Christoph Schick and his research group at the University of Rostock on the thermal analysis of polymers by fast differential scanning calorimetry (FSC). This past fall Professor Cebe's graduate students, Nelaka Govinna and David Thomas, accompanied her for two weeks to conduct experiments relevant to their own research projects. FSC allows for thermal measurements of samples at heating and cooling rates in excess of 4,000 K/s compared to the upper limit heating rate of 0.5 K/s accessible in conventional differential scanning calorimeters. Utilizing high rates allows for the study of materials which undergo thermal degradation near their melting points or have rapid phase change kinetics. Their work was focused on the study of polymer thin films and nanofibers suitable for applications ranging from tissue scaffolds to membranes for oil and water separation. Samples for the trip were prepared from both commercially available polymers as well as novel copolymers synthesized by our collaborators in Professor Asatekin's research group in the Chemical & Biological Engineering Department here at Tufts. The trip was highly productive with data being collected on a variety of polymers as well as the successful employment of our newly developed methodology to study nanofibers in a fast scanning calorimeter. Nelaka and Dave will be presenting on their results from these experiments at the upcoming March Meeting of the American Physical Society in New Orleans, Louisiana.

Goodbye to Friend and Colleague Allen Everett
June 2016

The Department of Physics and Astronomy notes with sorrow the passing of our esteemed friend and colleague Allen Everett.

Allen joined the Tufts Physics Department faculty in 1960, just after he completed a PhD in theoretical physics at Harvard. His early research was in the areas of nuclear and high energy physics, including the structure of the deuteron and the S-matrix approach to fundamental interactions. He was chair of the department between 1977 and 1980, and during this time recruited two theoretical physicists with interests in general relativity and theoretical cosmology, Alex Vilenkin and Larry Ford. Allen soon switched his attention to these areas, and the three of them founded the Tufts Institute of Cosmology, the first center in the United States devoted to theoretical cosmology. The Center has since achieved international prominence.

Allen and his colleagues sought to apply fundamental principles of particle physics to understand the processes in the early universe that gave rise to the universe that we see around us today. Allen researched the effects of phase transitions earlier in the history of the universe in forming topological defects, like cosmic strings and domain walls. The search for such defects still continues, and their detection would provide information about particle physics at the highest energies and about the early universe. Later he turned his attention to the deep question of the limits which the laws of physics place on faster than light travel and time travel. He did not seriously expect that these exotic effects actually occur in nature, but did believe that we can learn a great deal by probing the limits of physics and understanding why time travel is difficult or impossible.

Allen was also a dedicated teacher who cared deeply about the success of his students, and sought to give them an understanding of the key principles of physics. For several years, he taught an introductory calculus based physics course taken by all science and engineering majors at Tufts. He developed a course on time travel which appealed to a broad range of students, including those majoring in non-science areas. This course combined science fiction and a study of the basics of relativity theory. After his retirement in 2004, he built on that experience and his research to coauthor with Thomas Roman a book, "Time Travel and Warp Drives: A Scientific Guide to Shortcuts through Time and Space," which explains to non-experts what the laws of physics do say about faster than light travel and time travel. In recent years all graduating seniors in physics and astronomy have received a copy as a gift from the department.

Allen's generosity to Tufts, Tufts students, and the Department of Physics and Astronomy did not end with his retirement. In the past few years he made substantial financial donations to secure the future of the Institute of Cosmology and endow a room in the department's new home at 574 Boston Ave. With characteristic humility, Allen insisted that both of these contributions be in the name of his late colleague Allan Cormack.
